Pull request overview

Adds Buildkite CI support for qdb-api-python by introducing a dynamic pipeline generator, step templates, and a Docker-based Linux build environment (plus wiring in shared CI tooling via submodules).

Changes:

• Introduce a Buildkite dynamic pipeline generator (.buildkite/pipeline.py) with platform/build-type/python-version expansion.
• Add a Dockerfile and docker-compose config to run Linux builds/tests in a manylinux container.
• Wire in shared Buildkite tooling as a git submodule and add Buildkite-specific Python requirements.

set-python-version.sh only appends a PATH export to ~/.bashrc and sets PATH within its own RUN layer; that doesn’t reliably affect non-interactive bash scripts/... commands later when the container is used. If the intent is to make the selected /opt/python the default, set it via ENV PATH=... (or set PYTHON_CMD/PYTHON_EXECUTABLE explicitly) so the version is active for subsequent commands.

Pre-approved, but could we already use ~/scripts/cicd/ instead of ~/scripts/teamcity/? Maybe just symlink or something like that, so that we can write the buildkite templates consistently.

Not required, but nice to have.
